IMPORTANT SAFETY INSTRUCTION
• Open the circuit by cutting or brazing.
• The refrigerant charge should be recovered
into the correct recovery cylinders. The system
should be ushed with OFN to render the unit
safe. This process may need to be repeated
several times. Compressed air or oxygen shall
not be used for this task.
• Flushing should be achieved by breaking the
vacuum in the system with OFN and continuing
to ll until the working pressure is achieved, then
venting to atmosphere, and nally pulling down
to a vacuum. This process shall be repeated until
no refrigerant is within the system.
• When the nal OFN charge is used, the system
shall be vented down to atmospheric pressure
to enable work to take place. This operation
is absolutely vital if brazing operations on the
pipework are to take place.
• Ensure that the outlet for the vacuum pump is
not close to any ignition sources and there is
ventilation available.
CHARGING PROCEDURES
• In addition to conventional charging procedures,
the following requirements should be followed.
Ensure that contamination of dierent
refrigerants does not occur when using charging
equipment. Hoses or lines should be as short as
possible to minimize the amount of refrigerant
contained in them.
• Cylinders should be kept upright.
• Ensure that the refrigeration system is earthed
prior to charging the system with refrigerant.
• Label the system when charging is complete (if
not already).
• Extreme care should be taken not to overll the
refrigeration system.
• Prior to recharging the system, it should be
pressure tested with OFN. The system should be
leak tested on completion of charging but prior
to commissioning. A follow up leak test should
be carried out prior to leaving the site.
DECOMMISSIONING
• Before carrying out this procedure, it is essential
that the technician is completely familiar with the
equipment and all its detail. It is recommended
good practice that all refrigerants are recovered
safely. Prior to the task being carried out, an oil
and refrigerant sample should be taken in case
analysis is required prior to re-use of reclaimed
refrigerant. It is essential that electrical power is
available before the task is commenced.
• Become familiar with the equipment and its
operation.
• Isolate the system electrically.
• Before attempting the procedure ensure that:
• When breaking into the refrigerant circuit
to make repairs or for any other purpose,
conventional procedures should be used.
• Mechanical handling equipment is available,
if required, for handling refrigerant cylinders.
• Personal protective equipment is available
and being used correctly.
• The recovery process is supervised at all
times by a competent person.
• Recovery equipment and cylinders conform
to the appropriate standards.
• Pump down refrigerant system, if possible.
• If a vacuum is not possible, make a manifold so
that refrigerant can be removed from various
parts of the system.
• Make sure that cylinder is situated on the scales
before recovery takes place.
• Start the recovery machine and operate in
accordance with manufacturer’s instructions.
Do not overll cylinders. (No more than 80 %
volume liquid charge).
• Do not exceed the maximum working pressure
of the cylinder, even temporarily.
• When the cylinders have been lled correctly
and the process is completed, make sure that
the cylinders and the equipment are removed
from the site promptly and all isolation valves on
the equipment are closed o.
• Recovered refrigerant should not be charged
into another refrigeration system unless it has
been cleaned and checked.
WARNING
(For using R290/R32 refrigerant only)
